PAD-MACHINE.

Specification of Letters Patent.

Patented Dec. f4, T9115.

Application filed September 14, 1910. Serial No. 582,066.

To all whom it may concern:

Be it known that I, ALBERT 1D. ALEXAN- DER, a citizen of the UnitedStates, residing at Fredericksburg, in the county of Spottsylvania andState of Virginia, have invented certain new' and useful Improvements inPad-Machines, of which the following is a specification.

My invention relates to pad machines, and more particularly for makingthat class of pads used in packing furniture, and the like, in whichexcelsior or analogous material is used. y W

The object of the invention is to so construct the same that it may beconnected with an excelsior machine, the material from the excelsiormachine be received by the device and by the mechanism thereof may beproperly directed and distributed upon the paper, the glue automaticallyapplied, and the pad delivered from the machine and cut into properlengths. I

A further object of the device is to make a simple, cheap, and easilyconstructed device that will have as few parts as possible, that can beeasily assembled and repaired when necessary, and one in which single ordouble pads may be manufactured, as desired.

In the drawings forming a part of this specification, and in which likesymbols of reference represent corresponding parts in the several views:Figure 1 is a sectional side elevation of the machine; Fig. 2 a similarview to Fig. 1, showing the picker cylinder and filling chamber; Fig. 3a front view of the knife and its operating mechanism; Fig. 4 a frontview of the filling chamber showing the regulating sides; Fig. 5 a planview of the folder; and Fig. 6 a view of the glue pot.

1 is a power belt leading from the pulley 2, driven by any suitablepower; 3 the picker-shaft to receive motion from the same; 4 thepicker-head; 5 the casing surrounding the picker-head; and 6 the springto hold the hinged support 58in place.

7 is a band communicatingmotion to the pulley 8; 9 a sprocket-chainconnecting picker-shaft 3 with speed change pulley 10, said pulleys 10and 11 being adjustable speed pulleys operating by friction, to regulatethe speed of the device and 12 a chain belting for delivering theexcelsior from the excelsior machine.

13- is a press belt to hold the excelsior on the feed belt; 14 and 15are supporting timbers of the device; 16 base timbers connected to thesame; and 17 upper platform of the same.

The feed belt 12 and presser belt 13 are preferably located between twobrace timbers, not shown connected to the vertical support 14.

18 is a presser roller to hold the excelsior as it passes to the pickercylinder.

19 is the filling chamber in which the excelsior is received anddelivered to the paper, said chamber having wings 20 and 21, shown inFig. 4, for the purpose of regu-. lating and properly distributing theexcel- S101. This chamber may be used in any machine.

22 are the hinges supporting said wings and permitting regulation of thesame; 23 a bar contacting with the wings and 24 thumb nuts for adjustingthe bars and holding the wings in their adjusted position.

25 and 26 are bars and 27 and 28 thumb nuts for bracing and holding theframe of the filling chamber.

29 and 30 are the glue pots regulated by valves 31 and 32.

The glue feeds into a perforated cylinder 33, shown in Fig. 6. The paper34 and 35 is fed over the cylinder 33 and receives at its edges theglueas it is delivered from the glue pots. When a single pad is to be madeonly one paper strip is used; but when a double pad is desired, the twostrips are brought into requisition. The excelsior is fed between therolls 36 and 37 and passes down between rolls 38 and 39, the paper beingon both sides of the same. Rollers 37 and 39 are journaled in a hingedsupport 58, which is connected to the main frame by hinge 59; saidsupport being held in place by a spring 6, heretofore referred to.

40 is a presser roller to hold the paper down, and 41 a folder inproximity to the same, said folder being pivoted at 42 to the frame, sothat its forward part, which has overhanging or depending edges dipsdown and contacts with the edges of the paper and curls the border ofthe same. The float is, preferably, three-fourths of an inch thick, andits inclined or overhanging edge is, of course, more inclined at oneside to give the initial turn to the paper and thus permit one side tobe received within the other, to make a fold. In a single pad the edgesare folded upon each other, and in a double pad suficient of the edgesturned to permit the supplemental strip being connected to the same. Ofcourse this presser roller 40 will be of a width in accordance with thesize of the pad desired.

43 and 44 are rolls operated by sprocket chains 45 and 46, which areoperated from the driving mechanism, for delivering the paper pads uponthe belt carrier 47.

48 is a knife which automatically severs the pads at a predeterminedtime as they are delivered from the machine. This knife is normally heldraised by a spring 19, but as the sprocket chain 50 is operated throughthe medium of sprocket chain 51 the lug 52 comes in contact withcross-bar 53 of frame 54, which carries the knife, and lifts theknife-frame against the power of spring 49, so that when the lugreleases the frame the spring causes the knife to descend upon the padand sever the same.

55 are links connecting spring 49 with cross-bar 53.

56 is a sprocket wheel fOr operating sprocket chain 51, the samereceiving power from sprocket wheel 57 on change pulley 11.

The operation of the machine will be apparent from the foregoingdescription. The

excelsior is received, as it is delivered from the excelsior machine,upon the feed chain belting 12 and passes up onto the picker head whenceit is delivered into the filling chamber and properly distributedthrough the medium of the rolls upon the paper; in the meantime the glueis being automatically applied and the pad is severed by the knife anddelivered upon the carrier belt.

Having now described my invention, what I claim as new and desire tosecure by Letters-Patent, is

1. he pad machine, the combination'with means for delivering fillingmaterial to the same, of paper strip supplying means, valvecontrolledglue pots having perforated cylinders connected to the same to guide thestrip and spread the glue thereon, and means for directing the fillingmaterial on the pasted strip.

2. In a pad machine, the combination with means for delivering thematerial to the same, of a picker head to receive and distribute the'material, a filling chamber to receive the material, rolls to deliverthe paper and the material on the same, including fixed rolls andmovable rolls cooperating therewith, a hinged support carrying thecooperating rolls, and a spring at the upper portion of said hingedsupport to normally hold the movable rolls in contact with theircompanion rolls.

8. In a pad machine, the combination with means for delivering thefilling material to the same, of a picker head to receive'the material,a filling chamber to receive and regulate its supply, means for feedingthe paper strip forward, glue pots having perforated cylinders connectedtherewith for spreading the paste upon said strip, rolls to deliver thefilling material to the pasted strip, means for normally holding therolls in contact, and an oscillating folder provided with overhangingedges adapted to curl the paper and form the pad.

4. A pad machine, comprising means for conveying the material to thesame, means to regulate its supply, rolls to feed the paper andmaterial, means for supplying the glue, a presser'roll for the paper, aconverging folder toform the pad, a chain carrying a lug, aknife adaptedto be operated by the lug, a frame journaled in the machine and carryinga knife, a spring to hold the frame normally suspended, and connectingmeans between the various rolls, so that they may all be operated fromthe common source of power.

In testimony whereof I afiix my signature in presence of two witnesses.

ALBERT D. ALEXANDER.
